Hi Vijay

Steps to upgarde kernal:

Best practice to go ahead is:

Step 1: Create a new folder /sapmnt/<SID>/newkernel

Step 2: Copy all contents of /sapmnt/<SID>/exe to /sapmnt/<SID>/newkernel

Step 3: Download the database independent & database dependent files.

Step 4: Uncar these files in /sapmnt/<SID>/newkernel (This will overwrite old kernel files from newkernel, thus upgrading the kernel)

Step 5: Shutdown SAP & Database (Make sure all process are stopped e.g. saposcol, Database listener, etc)

Step 6: Rename /sapmnt/<SID>/exe to /sapmnt/<SID>/oldkernel

Step 7: Rename /sapmnt/<SID>/newkernel to /sapmnt/<SID>/exe

Step 8: Start Database & SAP system (Make sure you upgrade the kernel files on Application server as well)

Incase, you require to revert back to old kernel, just Bring down SAP & database copy back the exe folder to newkernel & oldkernel folder to exe)

any querry feel free to ask

Hi Vijay

Go to http://service.sap.com/sp-stacks

You need to download 2 car files from SAP Service Market: Database independent and Database dependent, usually SAPEXE.CAR and SAPEXEDB.CAR and uncar them into the kernel diretory.

You have to select kernal files based on ur OS and DB combination.

Also reward points its keeps the spirit of forum alive

Hi,

SAPEXE.SAR is the kernel independent file.

SAPEXEDB.SAR is the kernel dependent file. It is selected on the basis of the info you have selected about your OS and the database.

Regards, and don't forget to reward wit points. Keep the forum alive.

Hi Vijay

Bingo ur absolutely right.

Kernal consist of all executables like disp+work.exe,sapcar -xvf...etc.

Before going to apply the kernel patch we need to take the backup of run directory.And we need to stop all the sap services.

Here we have 2 types of kernnel.

1.Database dependent.

2.Data base independent patches.
